hadn't really thought about that, but also looking at it... his size comparison to that fortress.... Colossal is 30 ft long or more, so technically it has no limit, but still that dragon would have to be like 1000 ft long.

Dragons in D&D are rarely described in ways that match the rules write-ups. It's not uncommon to see dragons described as having fangs 6 feet long, claws of a similar length, or individual scales each the size of a shield. But think about how big that would make a dragon... And even if you go for the smaller numbers, like 30 feet -- think of how many coins it would take for a 30' body to be able to make a bed out of them, and then compare that to the treasure tables.
